To evaluate the change of retinal nerve fiber layer(RNFL) thickness measured with optical coherence tomography(OCT) following acute traumatic optic neuropathy.
From Feb. 2008 to Dec. 2009, 28 patients who had unilateral decreased visual acuity diagnosed as a traumatic optic neuropathy were evaluated about the progressive axonal change of RNFL thickness with disc OCT. 12 eyes of 28 patients were checked serial disc OCT after acute trauma and RNFL thickness were obtained with disc OCT every two weeks for six weeks and on the 12week after trauma.
The mean age of 12 patients was 48.58 ± 21.64 years. The mean RNFL thickness of at the second week after trauma was 95.03 ± 5.93 µm and reduced sequentially over the 6 months and it was 50.61 ± 5.99 µm. During first 6 weeks, the reduction rate of RNFL thickness was faster than other period and it became stable at 6th month after trauma. The superior and inferior portion of disc showed more rapid reducdtion of RNFL thickness than other area,
We found that RNFL thickness decreased sequentially until 6 month, mainly first 6 weeks after trauma in traumatic optic neuropathy.
